SHUTTLE-OPERATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 778,378, dated December 27, 1904. Application filed June 12, 1902. Serial No. 111,426.

1'0 (ZZZ whom it mag concern.-

Be it known that I, Gnone SoHwABn, a subject of the Emperor of Austria-Hungary, re-

siding at Bielitz, Silesia, Austria-Hungary,

have invented certain new and useful Improvements in Shuttle-Operating Devices, of which the following is a specification.

This invention relates to an improved shuttle-operating device for looms which economizes power and reduces wear.

In the accompanying drawings, Figure l is a front view of part of a loom embodying my invention, and Fig.2 a detail side view thereof.

To the right-hand side of the loom frame A is pivoted at A a segment a, that receives oscillating motion from a pitman b, pivoted to the segment at b. To segment a is secured at 0 one end of a first spiral spring d, the other end of which is connected to frame Aat a Further, there is secured to segment a at f one end of a second spiral spring the other end of which is connected to, the 'picker=stick k at e'. Upon pivot A oscillates an arm h, carrying a pawl m, that engages a tooth d of segment a. To arm it is pivoted at I? one end of a strap 00, the other end of which is connected to the picker-stick in the usual manner.

The mechanism described is duplicated substantially for the left-hand side of the loom. To segment a is pivoted at Z a rod Z, that in turn is connected at f to a segment a, pivoted at A to frame A. A spiral spring d is connected to pin 0' of segment a and to pin 6 of frame A. A second spring g is connected to segment a at f and to picker-stick k at i; Upon pivot A is free to turn an arm h, carrying a pawl m, that is adapted to engage a tooth a of segment a. To arm it is connected at b the strap a? of picker-stick in.

The operation is as follows: If pitman-Z) moves in the direction of the arrow, Fig. 1, segment a will turn on pivot A and rod Z will impart a corresponding movement to segment a, so that both segments move simultaneously in opposite directionsc'. eL, inward with their upper ends. As teeth a and a are In engagement w1th pawls-m and m of arms 7a and/t,

' respectively, the motion of segments a and a will be transmitted to the arms h and 7t. These arms in turn transmit motion by straps 00 andaz to the picker-sticksle and is, so as to throw the shuttle.

Fig. 1 illustrates the position of the parts when the picker-sticks are, in their extreme In this position springs (Z' and cl are distended, and consequently they outward position.

scends, so that segments a and a return to their original-position. At the same time the picker-sticks are swungoutward by means of the springs g and g. During their outward movement'the picker-sticks run empty, and consequently require less operative power than when moving inward. The surplus of operative power acting upon the outwardlymoving picker-sticks is consequently stored up in the springs'd cl, and thus utilized for assisting the pitman in moving the pickersticks inward and driving the shuttle. In this way the power required for operating the loom is equalized and reduced to a considerable extent.

What I claim is 1. In a loom, the combination with a driving-gear, two rocking shafts,two picker-sticks, and link connections between the sticks and the shafts, of a curved spring-influenced seg ment on one of said rocking shafts, a pitman and connections thereof with the driving-gear and with one end of said curved segment, a two-arm lever on the other rocking shaft, and

a connecting-rod linked respectively to the other end of the curved segment and to one end of said two-arm lever, substantially as specified.

2. In a loom, the combination of a'frame with an oscillating segment, a pivoted pickerstick, a first spring between segment and frame, a second spring between segment, and picker-stick, and means for connecting the segment to the picker-stick, substantially as specified.

Inwitness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

GEORG SCHWABE.
